A gift was just given to me. They are the Logitech Z623 speakers. But, they came with no documentation. When I plug them in as intended with either my HDTV or my desktop pc, only one of the satellite speakers worked and the other did not along with the bass not sounding as I thought it should. The system did not come with an input cable that connected the system to the input device, so I just used one that plugs into the speaker output of the device and connects to the Left/Right connectors, and I do not know what the music symbol stands for. Does anyone have the setup and/or user documentation for this set of speakers? the support website for Logitech does not offer this. Strange. I just want to find out if I am missing something or if the system is just broken. Thank you in advance.

If your computer came with a motherboard disc the sound drivers could be on it
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers or uninstall
click start control panel sounds and audio,volume,advanced,speakers make sure you have selected the
(((appropriate speakers))) also audio you will find 3 drop down lists make sure you have the correct settings there
also
click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it
click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar
if his does not fix the problem

have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer
hope this helps

I checked Logitech's website and they don;t have any downloadable documentation for this product. Anyway, let's just try and fix it.

First, make sure your left and right speakers are connected properly to the bass speaker.

Next, the wire from the bass should be connected to your soundcard's line out port (light green) or into your TV's audio lineout.

You can also adjust the volume of your bass separately on the right speaker.

Update me if this worked or if you are still having trouble.

Thanks for using Fixya!
